In my post about human lung tissue showing cancer cells, jswatts speculated that the blue masses might be cartilage. Here is an image of hyaline cartilage. The cartilage is in the center. The tissue to the right appears to be a cross section of muscle tissue. http://www.photomacrography.net/forum/us...

This is lung tissue but the slide is not marked as to whether it is human or not. I have a cartilage slide which I will post tomorrow so we can compare. http://www.photomacrography.net/forum/userpix/2226_Healthy_lung_tissue_1.jpg Since we are challeneged for winter specimens in the Northern Hemisphe...

Very nice. Is this the dry paper-like skin on the bulb?

I found a procedure for silver staining online.
First fix the section with formaldehyde or gluteraldehyde for a couple of days and then immerse the section in 2% silver nitrate for two days.
Pau, the color balance with the One-Touch White Balance is working well so far.

I have other slides of human human lung tissue which I will post. The others show large areas clear of tissue. The blue cells look very much like the cancer I see in a Caposis Sarcoma slide I have. I've been accumulating histology slides for several years through online auctions and have a diverse s...

Human Bone thin cross section silver stained. Bone and nerve tissue are most commonly silver stained. I have some silver nitrate in my darkroom and want to find a formula for silver stain when I get my microtome up and running.

On New Years Eve my wife struck and killed a four-point buck with her van. Lots of damage to the front end of her van. There were some hairs stuck in the damaged fender and I mounted a few in balsam on a slide. We live in a mountainous wooded area south of Allentown, Pennsylvania. The Pennsylvania G...

Pau, I had been using a Custom White Balance at 4000 K on my scope. But now i am trying a One-Touch White Balance on my Olympus E-420. For those of you not familiar with One-Touch White balance, you are able to shoot a white frame with the camera and it saves the white balance as a neutral gray in t...

NikonUser is recommending f8 over f32 because at f32 lens diffraction can seriously wipe out detail. The sweet spot on most lenses is usually a middle stop -- f8 or f11. You will have to have more shots in your stack, but the detail will be much finer.

While I'm not a pathologist, by comparing myslides of healthy lung tissue which are absent the large bluish masses, I conclude the bluish cell massses are cancerous. I have seen similar cell masses on other histology slides of cancers.

Looks like the slide is mislabeled.
